"The Eucharist, finally, also teaches that our present experience of God's presence and blessing is incomplete. We have tasted that the Lord is good, sampled a bit of the heavenly gift; we have entered into the sanctuary (Heb. 6:4-6). But we are not yet filled. Like eating popcorn, the Supper just makes us want more. The taste makes us long all the more for the consummation of the promise, when we shall see God face-to-face, know even as we are known, and sit with Him at His table in the eternal kingdom of heaven."
(Jeff Meyers, The Lord's Service, p 226)
